Charts, Documents & Visualization

🟢 Beginner friendly — produces files on your machine. No funds move.

The agent can produce visual artifacts: ECharts interactive charts, Word/PDF/PowerPoint documents, and analyze uploaded chart images for technical patterns.

What you can do

• Chart generation: price charts, comparison charts, portfolio pie charts
• Technical analysis from images: upload a K-line screenshot for TA
• Document generation: Word, PDF, and PowerPoint report deliverables
• Spreadsheet creation: data tables and analysis exports
• Data visualization: any structured data rendered as a chart

Example prompts

create a chart comparing BTC and ETH performance over 6 months
analyze this chart [upload screenshot] — what patterns do you see?
generate a PDF report of my portfolio performance
create a spreadsheet of the top 20 DeFi protocols by TVL

Example output — chart generation

Prompt: create a chart comparing BTC and ETH performance over 6 months, indexed to 100 at start

Agent response:

Creating interactive ECharts visualization…

Chart is ready: BTC vs ETH, 6-month indexed.

Data summary (2026-10-17 → 2026-04-17):

• BTC: 100 → 138.5 (+38.5%)
• ETH: 100 → 125.7 (+25.7%)
• BTC outperformed by 12.8 percentage points
• BTC max drawdown: -14.2% (Jan 2026)
• ETH max drawdown: -21.4% (Jan 2026)
• Correlation: 0.82 (strong, as expected)

At turn end, the chart reference resolves to three files in the sandbox:

📎 Artifacts
   📊 BTC vs ETH, 6-month indexed
      html → file:///…/sandbox/files/artifacts/x-a3b48f/chart-x-a3b48f.html
      json → file:///…/sandbox/files/artifacts/x-a3b48f/chart-x-a3b48f.json
      png  → file:///…/sandbox/files/artifacts/x-a3b48f/chart-x-a3b48f.png

• HTML — self-contained page loading ECharts from the public CDN. Open in a browser to interact with the chart (tooltips, legend toggles, zoom).
• JSON — raw { charts: [...] } options you can drop into any ECharts viewer or embed in your own app.
• PNG — rendered at 2× DPR by Playwright. Best-effort: if Chromium isn't installed, HTML and JSON still land and PNG is skipped with a log warning.

Example output — TA from image

Prompt: analyze this chart [upload 4h BTC chart screenshot]

Agent response:

4-hour BTC chart, pattern analysis:

1. Ascending triangle forming since April 10 — horizontal resistance at $68.2k, rising support from $63.4k lows.
2. Volume profile: declining on each retest of resistance (textbook accumulation setup — not confirmed yet).
3. RSI-14: 58 — room to run before overbought.
4. Projected breakout target: $68.2k + (triangle height $4.8k) = $73.0k measured move.

Caveats: ascending triangles fail ~30% of the time, especially on lower timeframes. Confirm with a 4h candle close above $68.4k on rising volume before treating this as a real breakout.

Example output — PDF report

Prompt: generate a PDF report of my portfolio performance over Q1

Agent response:

Compiled a Q1 performance report. Sections: holdings overview, realized vs unrealized P&L, top contributors, drawdown breakdown, and a risk commentary.

Written to reports/portfolio-q1-2026.pdf (7 pages, 142 KB).

📎 Artifacts
   📄 Portfolio — Q1 2026
      pdf → file:///…/sandbox/files/reports/portfolio-q1-2026.pdf

PDFs are produced by the pdf_create tool (pdf-lib, MIT). Text-only output, wrapped for Helvetica at letter size. The agent passes a { title, sections: [{ heading?, paragraphs }] } payload.

Example output — Word (DOCX) memo

Prompt: write a DOCX memo summarizing the top 5 DeFi protocol risks

Agent response:

Drafted a five-section memo. Each risk has a one-paragraph explanation plus a mitigation note. Kept headings at H2 so you can paste into any template.

Written to memos/defi-risks.docx (5 sections, 18 KB).

📎 Artifacts
   📄 DeFi protocol risks — memo
      docx → file:///…/sandbox/files/memos/defi-risks.docx

DOCX is produced by docx_create (docx npm, MIT). Shape is the same { title, sections } as PDF — the two tools share an input contract so you can ask for either format interchangeably.

Example output — Spreadsheet (CSV)

Prompt: create a CSV of the top 20 DeFi protocols by TVL

Agent response:

Pulled the top 20 from DefiLlama. Columns: rank, protocol, chain, category, TVL (USD), 7d change, 30d change. Sorted by TVL desc.

Written to data/defi-top20-tvl.csv (21 rows including header).

📎 Artifacts
   📊 DeFi top-20 by TVL
      csv → file:///…/sandbox/files/data/defi-top20-tvl.csv

Spreadsheets are emitted as CSV via the write_file tool into the sandbox. For a richer format (formulas, multi-sheet, styled cells), ask for a PDF or DOCX report that embeds the table — the document tools handle layout, and the data comes from the same DefiLlama / market-data skills.

XLSX note: the agent does not natively generate .xlsx files — CSV covers the analytical-export use case at a fraction of the dependency weight. XLSX is supported as an input: upload a spreadsheet and the spreadsheet parser converts it to structured text the agent reasons over.
